its hard to say really, i feel like some people may struggle to align the camera to view the pictures properly, here's a camera constrained version but doesn't allow me to zoom any further since the center point has to be in the middle or the room:

Thats it i'm finished cant do camera constraints with the annotation so I've artificially made the centre of the model the middle of this circular room, so that orbiting movements circle the middle of the room. The sounds seem to work so i'm leaving them alone now!

Hey thanks, nah the curtain was simulated with massfx in max, then baked out to morthtarget frames using a maxscript, the window lights were subtley animated by hand, and the floor highlights move too but im sure thats barely noticable found the secret message?
